在Windows上移除Highchart数据标签调整大小 [英] Removing Highchart datalabels on windows resize
问题描述
我一直试图使用Highcharts来实现饼图,但是在裁剪出非常低的分辨率时遇到了数据标签问题。
我试图添加一个窗口使用格式化程序.resize:function()但失败。
以下是我目前使用的代码:
//放大颜色
Highcharts.getOptions()。colors = $ .map(Highcharts.getOptions()。colors,function(color){
return {
radialGradient:{cx:0.5,cy:0.3,r:0.7},
stops:[
[0,color],
[1,Highcharts.Color(color ).brighten(-0.3).get('rgb')] // darken
]
};
});
//构建图表
图表= new Highcharts.Chart({
图表:{
renderTo:'container',
plotBackgroundColor:null,
plotBorderWidth:null,
plotShadow:false,
backgroundColor:{
linearGradient:[0,0,500,500],
stops:[
$ b $
title:{
text:'Header Here'
},
tooltip:{
pointFormat:'{series.name}:< b> {point.percentage}%< / b>',
percentageDecimals:0
},
plotOptions:{
pie:{
allowPointSelect:false,
cursor:'pointer',
dataLabels:{
enabled:true,
color:'#000000',
connectorColor:'#000000',
formatter:function (){
return'< b>'+ this.point.name +'< / b> ;:'+ Math.round(this.percentage)+'%';
}
}
}
},
系列:[{
type:'pie',
name:'Votes',
data:[
['Vote One',50],
['Vote Two',50],
['Vote three',2]
]
}]
});
除了在调整大小时创建新图表之外,还有其他方面可以将标签设置为false / hidden ?并再次显示超过特定分辨率?
非常感谢
您可以将useHTML设置为true来标记数据标签,并在formatter中定义您自己的div。然后,当你捕捉调整大小的事件使用显示/隐藏functons。
简单的例子显示/隐藏数据标签后点击按钮可在这里:
chart = new Highcharts.Chart({
图:{
renderTo:'container',
type:'line'
},
title:{
text:'Monthly Average Temperature'
},
plotOptions:{
series:{
dataLabels: {
enabled:true,
useHTML:true,
formatter:function(){
return'< div class =datalabel>'+ this.y +' < / div>';
}
}
}
},
系列:[{
data:[7.0,6.9,9.5,14 ($)
$('#btn',
$ ).toggle(function(){
$('。datalabel')。hide();
},function(){
$('。datalabel')。show();
});
});
I have been trying to implement the pie chart using Highcharts but am encountering an issue with the datalabels on very low resolutions being cropped.
I have attempted adding a windows.resize withing the formatter: function() but that failed.
Here is the code I am currently using:
// Radialize the colors
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function(color) {
return {
radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 },
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken
]
};
});
// Build the chart
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
backgroundColor: {
linearGradient: [0, 0, 500, 500],
stops: [
]
},
},
title: {
text: 'Header Here'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage}%</b>',
percentageDecimals: 0
},
plotOptions: {
pie: {
allowPointSelect: false,
cursor: 'pointer',
dataLabels: {
enabled: true,
color: '#000000',
connectorColor: '#000000',
formatter: function() {
return '<b>'+ this.point.name +'</b>: '+ Math.round(this.percentage) +'%';
}
}
}
},
series: [{
type: 'pie',
name: 'Votes',
data: [
['Vote One', 50],
['Vote Two', 50],
['Vote three', 2]
]
}]
});
Is there anyway other than creating a new chart on resize that the labels can be set to false / hidden? and shown again above a certain resolution?
Many thanks
You can set useHTML as true for datalabels and in formatter define your own divs. Then when you catch resize event use show / hide functons.
Simple example which show/hide datalabels after click button is available here:
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'Monthly Average Temperature'
},
plotOptions: {
series: {
dataLabels: {
enabled: true,
useHTML: true,
formatter: function () {
return '<div class="datalabel">' + this.y + '</div>';
}
}
}
},
series: [{
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}]
}, function (chart) {
$('#btn').toggle(function () {
$('.datalabel').hide();
}, function () {
$('.datalabel').show();
});
});
